[Unbound-users] cache-min-ttl

 I am confused about the option cache-min-ttl. u-control will not let
me set or get the option. I have a value set in my conf file and
u-checkconf does not print any errors regarding the option. However
u-checkconf will not print the value.

What follows is a transcript of my debugging attempts:
